Cosa (chi) è Hardware handshaking - definizione

USE OF SPECIALIZED COMPUTER HARDWARE TO PERFORM SOME FUNCTIONS MORE EFFICIENTLY THAN IS POSSIBLE IN SOFTWARE RUNNING ON A MORE GENERAL-PURPOSE CPU
Hardware accelerator; Accelerator board; Hardware mixing; Acceleration hardware; Hardware-accelerated; Hardware Acceleration; Hardware accelerators; Hardware accelerated; Hardware acceleration (computing)
  • A [[cryptographic accelerator]] card allows cryptographic operations to be performed at a faster rate.

hardware handshaking      
<communications> A technique for regulating the flow of data across an interface by means of signals carried on separate wires. A common example is the RTS (Request to Send) and CTS (Clear to Send) signals on an EIA-232 serial line. The alternative, software handshaking, uses two special characters inserted into the data stream to carry the same information. (1995-01-23)

WIKIMEDIA DISAMBIGUATION PAGE
Hardware system; Hardware System; Hardware (disambiguation); H/W; HARDWARE; Hardwares
<hardware> The physical, touchable, material parts of a computer or other system. The term is used to distinguish these fixed parts of a system from the more changable software or data components which it executes, stores, or carries. Computer hardware typically consists chiefly of electronic devices (CPU, memory, display) with some electromechanical parts (keyboard, printer, disk drives, tape drives, loudspeakers) for input, output, and storage, though completely non-electronic (mechanical, electromechanical, hydraulic, biological) computers have also been conceived of and built. See also firmware, wetware. (1997-01-23)

Hardware acceleration

Hardware acceleration is the use of computer hardware designed to perform specific functions more efficiently when compared to software running on a general-purpose central processing unit (CPU). Any transformation of data that can be calculated in software running on a generic CPU can also be calculated in custom-made hardware, or in some mix of both.

To perform computing tasks more quickly (or better in some other way), generally one can invest time and money in improving the software, improving the hardware, or both. There are various approaches with advantages and disadvantages in terms of decreased latency, increased throughput and reduced energy consumption. Typical advantages of focusing on software may include more rapid development, lower non-recurring engineering costs, heightened portability, and ease of updating features or patching bugs, at the cost of overhead to compute general operations. Advantages of focusing on hardware may include speedup, reduced power consumption, lower latency, increased parallelism and bandwidth, and better utilization of area and functional components available on an integrated circuit; at the cost of lower ability to update designs once etched onto silicon and higher costs of functional verification, and times to market. In the hierarchy of digital computing systems ranging from general-purpose processors to fully customized hardware, there is a tradeoff between flexibility and efficiency, with efficiency increasing by orders of magnitude when any given application is implemented higher up that hierarchy. This hierarchy includes general-purpose processors such as CPUs, more specialized processors such as GPUs, fixed-function implemented on field-programmable gate arrays (FPGAs), and fixed-function implemented on application-specific integrated circuits (ASICs).

Hardware acceleration is advantageous for performance, and practical when the functions are fixed so updates are not as needed as in software solutions. With the advent of reprogrammable logic devices such as FPGAs, the restriction of hardware acceleration to fully fixed algorithms has eased since 2010, allowing hardware acceleration to be applied to problem domains requiring modification to algorithms and processing control flow. The disadvantage however, is that in many open source projects, it requires proprietary libraries that not all vendors are keen to distribute or expose, making it difficult to integrate in such projects.
